Nanoparticles have emerged as one of the most sought-after materials finding application in various sectors. Synthesis of green nanoparticles have attracted extensive interest worldwide because of its biocompatibility and huge potential for utilization as catalysts, antimicrobial agents, in energy har vesting, cancer/gene therapy, sensing etc. Inherent properties of nano-materials such as specific size, shape, composition, greater surface area to volume ratio and purity of individual constituents makes it a fascinating multifunctional material. Diverse groups of living organisms (prokaryotes and eukaryotes) and biomolecules are increasingly being employed as bio-template for designing nanoscale materials. Characterization tools such as SEM, TEM, AFM, FTIR, XRD, NMR aid in unravelling their unique properties. This review provides a comprehensive overview of key findings in green synthesis of nanoparticles and attempts to determine their possible synthesis mechanism. This article also focuses on factors affecting their synthesis, characterization, applications, potential toxic impact on living organisms, merits/demerits and future prospects.
